| 摘 要： | 沙尘暴天气数值预报系统包括区域大气模式、陆面过程模式、风沙模式(包括风蚀、输送和沉降模式)和地理信息系统。用该系统对2002年3月20日和4月7日2次沙尘天气进行了预报试验，利用地面观测资料和卫星观测资料对模式输出的主要沙尘天气预报产品进行了对比分析。分析结果认为，沙尘暴天气数值预报系统对沙通量、尘通量和垂直积分质量有很好的预报能力，但仍需改进陆面参数和沙尘气溶胶的初始值。

| Abstract: | A dust storm forecasting experiment was conducted with a dust storm integrated forecasting system in the spring of 2002. The system includes a regional atmospheric model, a land-surface model, a wind erosion model, and a dust transport and deposition model. Geographic information data, such as soil type, vegetation height, fractional vegetation cover and leaf-area index, were used in the integrated forecasting system. By means of the numerical products of the integrated forecasting system, two case studies were conducted through analyzing sand flux, dust flux, vertically integrated mass, and so on. The results were compared with surface observation data and satellite images. The test results show that the system is feasible as a dust storm operational model. |
